x over -4 < 4
Graph the solution of the inequality;
A. is -16 to -4 and beyond
B. is -16 to -22 and beyond
You mean x/(-4) < 4?
You need to figure out when x/(-4) is ever greater than 4. Because the denominator is negative, it will never be as long as x is positive.
Wait -- I'm thinking two dimensions -- this is a line graph, correct?
It's a circle around -16 and highlight everything to the right.
I'm not sure what A and B are about. The answer is A.
The best way to figure this out if it is multiple choice is to plug in a number in the middle of the range. -8/-4 = 2 which is less than 4. -20/-4 is 5 which is greater than 4.
Hope that helps.
Alright, so this girl is in 7th grade and needs help with her homework.
I cannot remember how to solve this problem. If anyone can help solve this for me.. and explain to me how it was done so I can help in the future I'd appreciate it.
Stupid math skills not being used... *grumble*
Okay;
x over -4 < 4
Graph the solution of the inequality;
A. is -16 to -4 and beyond
B. is -16 to -22 and beyond
x/(-4) < 4
x(-1)/(-4) > (-1)(4)
Note: multiplying each side by (-1) reverses an inequality sign within an equation
x/4 > -4
Note: multiplying any quantity by (-1) changes the sign of that quantity.
Note: The inequality does not change here because this is merely the evaluation of the previously introduced (-1) multiple.
x (4/4) > (4)(-4)
Note: multiplying each side by the same positive constant preserves the inequality.
X > -16
I hope that explains how the equation was solved well enough. Of course, you may be well past this by now.
